My bb doesn't last for near as long as advertised. Does leaving the wireless feature on kill the battery fater? If I want to extend my battery's life, would I leave it off and then only turn it on when I want to check emails or get online?

If you are talking about the "Turn Wireless Off" icon, I think you will find that doing so will also disable your ability to make and receive phone calls. One quick fix would be to drop down your backlight brightness level, backlight timeout time, and turn off the LED coverage indicator. While each of these individual things may not burn a lot of battery power, changing the settings together may make a noticeable difference. Can't hurt to try.

You could also do a check to make sure you aren't running any programs that aren't essential. Some programs seem to drain the batter even when you're not using them, but they're running in the background.Hope this of some help.

to add the the above posts! Use the stand-by button! that is the mute button on the top of the phone press and hold it and then from there it will enter and save life as well as when you leave the browser hit the BB button and select close that is saving life cause you are not running programs you don't need! If this doesn't do it I know TMO cuase i work there that you can go and either have them send oyu out a new battery in the warrenty exchange! IT IS FREE! or see if they have a new one in returns and then ask to swap out with that battery! hope this helps!

Ok. I can do the standby thing. But if I can still get calls and emails, then what the difference between using standby and not using standby? Why wouldn't the phone just go into standby every time I don't use it for a little while?
